Ice Age Alaskan Steppe Bison (Bison priscus) leg bones

Fossil metapodial (leg) bones from extinct Ice Age Alaskan Bison for sale. These metacarpal/metatarsal bones were discovered in river silt in Kotzebue, Alaska, where they had come to light after lying hidden and protected by thick tundra ice for many thousands of years.

These Steppe Bison (Steppe Wisent, or Bison priscus) leg-bones date from the Pleistocene period (between 11,700 and 2,588,000 years ago), or soon after the beginning of the Holocene period (9,700 years ago) - when the Steppe Bison became extinct.

All bone specimens have been cleaned and sealed with a diluted layer of polyurethane lacquer. All were lightly brushed with water prior to photography.

Recent global warming means that more and more fossil specimens like these - along with Woolly Mammoth tusks and bones - are being unearthed in Alaska and Siberia.
